About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-20
The AirTAC SAIJ160X180-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty automation. By integrating a 20mm adjustment mechanism, this model provides a usable travel window of 160 to 180mm, allowing technicians to dial in the exact retract position without external stops. It features a SUS304 stainless steel rod and PT tapered port threads, ensuring high corrosion resistance and a reliable seal in demanding environments.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It is important to note that the rear adjuster functions strictly as a travel stop for end-position tuning, not as a load-holding device; true position retention without live air requires a SAIL or BSAI series cylinder.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-20 Is Used
Heavy Machinery Setup
Fine-tune the 160-180mm retract position during initial commissioning of large presses or heavy material handlers without swapping components.
Product Changeover
Quickly adapt end-stops on an automated line when introducing a new product size, utilizing the 20mm adjustment window for rapid validation.
Variable End-Stop Positioning
Dial in the exact retract distance for heavy-duty assembly stations, ensuring precise contact without bolting on external physical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-20 the Right Cylinder?
The adjustable stroke is specifically chosen for applications requiring fine end-position tuning during commissioning or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot match. When replacing an ISO 15552 cylinder, verify the 180mm stroke, 20mm adjustment, PT port type, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300mm, external side-load guides are less critical than with longer travels, but the robust 40mm rod and M36x2 thread handle substantial mechanical stress effectively.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-20 FAQ
The rear adjuster acts as an external stopper that allows you to shorten the effective stroke by up to 20mm. This creates a usable travel window between 160mm and 180mm, enabling precise end-position tuning at commissioning without replacing the cylinder.
